Color not accurate playing Youtube videos with 12.04LTS?

Suddenly a couple days ago I noticed color is off, very blueish, when playing videos on Youtube. When videos/movies are played from other sources color is normal and accurate. Anyone know what may have happened causing this?

I have a triple boot system running Win7, 12.04LTS and 14.04LTS
When W7 is run color is completely normal playing Youtube videos.
However color is off with blueish tinge on both 12.04 and 14.04.
Played around with 'enhancements' on Youtube which does correct color and goes back to normal but when I try 'saving' it doesn't hold the correction made! It goes back blueish when videos are played again.

sgunhouse, I Right-click on a Flash animation/video, get Adobe Flash Player Settings,
Enable hardware acceleration is checked off but it is Locked and I can't uncheck it or even close that settings page! I have to refresh it to close that Adobe Flash Player Settings box.

I've no idea what it depends on, but sometimes those items react on single clicks - like normal, but sometimes they don't.
Then one fine day, I discovered about double-clicking here and there (it pertains to ad windows on such sites/pages, too - I mean those blocking the played content).

Having trouble with other sites play vids.
While Opera 12 says Flash Player is installed and plays all fine.
Opera 25 beta says Sorry, Flash Player is not installed and won't play at all.
When attempting to install Flash 11 on Opera 25 Ubuntu Software Center says flash 11 is already installed!
